Did You Know?

A punctilio is a small point—a minor rule, or a little detail of conduct in a ceremony. A person who pays close attention to such minor details is punctilious. Punctiliousness can be valuable, especially for certain kinds of tasks, as long as you don't become so concerned about small points that you fail to pay attention to the large ones.
